It treats prostate, hepatocellular, lung, pancreatic, head and neck and sarcoma patients and has published widely on hypofractionated carbon-ion schedules and on radiobiology of high-LET radiation. The centre is linked to Gunma University's Graduate School of Medicine and to the Japan Carbon-ion Radiation Oncology Study Group (J-CROS), which pooled outcomes across Japanese facilities to support national insurance coverage for carbon-ion therapy.","asOf":"2026-09-09","links":[{"label":"Gunma University Heavy Ion Medical Center","url":"https://heavy-ion.showa.gunma-u.ac.jp"},{"label":"Gunma University","url":"https://www.gunma-u.ac.jp"},{"label":"PTCOG: particle therapy facilities in operation","url":"https://www.ptcog.site/index.php/facilities-in-operation-public"}],"tags":[],"related":[],"cancers":["prostate","hcc","pancreatic","sarcoma","head-and-neck"],"sections":["radiation"],"technologies":["carbon-ion","carbon-ion-synchrotrons"],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":["tatsuya-ohno"],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"city":"Maebashi","country":"JP","lat":36.397,"lng":139.061,"institutionType":"hospital","website":"https://heavy-ion.showa.gunma-u.ac.jp","university":"Gunma University","programs":["Carbon-ion therapy","Radiobiology of high-LET radiation","J-CROS multicentre outcomes"]},"route":"/institutions/gunma-heavy-ion-medical-center/","neighbours":{"cancer":[{"id":"head-and-neck","kind":"cancer","name":"Head and neck squamous cell carcinoma","route":"/cancers/head-and-neck/"},{"id":"hcc","kind":"cancer","name":"Hepatocellular carcinoma","route":"/cancers/hcc/"},{"id":"pancreatic","kind":"cancer","name":"Pancreatic ductal adenocarcinoma","route":"/cancers/pancreatic/"},{"id":"prostate","kind":"cancer","name":"Prostate cancer","route":"/cancers/prostate/"},{"id":"sarcoma","kind":"cancer","name":"Sarcomas (soft tissue, bone, GIST)","route":"/cancers/sarcoma/"}],"section":[{"id":"radiation","kind":"section","name":"Radiation Therapy","route":"/fronts/radiation/"}],"technology":[{"id":"carbon-ion-synchrotrons","kind":"technology","name":"Carbon-ion synchrotrons and facilities","route":"/technologies/carbon-ion-synchrotrons/"},{"id":"carbon-ion","kind":"technology","name":"Carbon-ion therapy","route":"/technologies/carbon-ion/"}],"person":[{"id":"tatsuya-ohno","kind":"person","name":"Tatsuya Ohno","route":"/people/tatsuya-ohno/"}],"institution":[{"id":"qst-hospital","kind":"institution","name":"QST Hospital (National Institutes for Quantum Science and Technology)","route":"/institutions/qst-hospital/"}]}}
